Shoulder joint - Anterior/posterior (English)

Three glenohumeral ligaments (superior, middle, inferior) form as a thickening of the articular capsule and connect the humeral head to the glenoid fossa of the scapula. The coracohumeral ligament connects the coracoid process of the scapula with the greater tubercle of the humerus and reinforces the superior portion of the glenohumeral articular capsule. The transverse humeral ligament extends between the lesser and greater tubercles and stabilizes the tendon of the long head of the biceps brachii muscle. Lastly, the joint is also stabilized by four muscles (supraspinatus, infraspinatus, teres minor and subscapularis muscles [faded]) collectively known as the rotator cuff which form a musculotendinous sleeve around the joint.
